Dear Ben Hutchings,
Dear kernel developers,

First I want to thank you all for your amazing work.
It moves me to see how you all work on this humongous project so successfully and coordinatedly.
I am not a kernel developer and I watch in awe how you accomplish all this.

Nonetheless, I plead for rolling back to the old test

	if (eeepc_wmi_check_atkd()) {...}

in eeepc_wmi_probe() that was in effect until kernel 4.6.7
rather than the new test

	if (acpi_dev_found(EEEPC_ACPI_HID)) {

used as of kernel 4.7.x
because the new test prevents loading eeepc-wmi
while the old one loads it,
just as Oscon has described.

I own seven boxes Eee PC 1001PXD

  https://www.asus.com/Laptops/Eee_PC_1001PXD/

and want to prepare them with Debian 9 and give them to people for free
who cannot or do not want to afford to buy a new laptop.
Also I want to encourage improving the current drivers for Asus EeePCs.

In order to support your work, I offer to send one or two of my boxes
for testing purposes to kernel and driver developers.

And, of course, I am willing to desribe all the relevant bugs
that I have encountered on these boxes in sufficient detail whenever required.

Please let me know how else I can support.
And, of course, I will pay the postage.

Cheers, and again thank you for your awesome work!

  Roland
